In the beautiful constellation Cassiopeia located 7,500 light years away from Earth, is a gorgeous star cluster called Melotte 15. It lies in the center of the famous Heart Nebula and extends for 30 light years.
The Heart Nebula, IC 1805, Sharpless 2-190, is located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. It was discovered by William Herschel on 3 November 1787. This is an emission nebula showing glowing ionized hydrogen gas and darker dust lanes.

The nebula's intense red output and its configuration are driven by the radiation emanating from a small group of stars near the nebula's center. This open cluster of stars known as Melotte 15 contains a few bright stars nearly 50 times the mass of our Sun, and many more dim stars that are only a fraction of our Sun's mass.

This nebula and star cluster was only formed 1.5 million years ago, which is still considered a baby in the universe time-scale. Who knows what planets and species may already be present in this part of the universe, or what the future may hold for this star cluster. For now humans can look upon this nebula and star cluster with a sense of wonder and appreciation for how incredible the universe is.
